Marking the examples as docs for rpm release is convenient because you can provide the --nodocs option to not install them. Some users won't care about the examples.
Though, perhaps we should put some thought into examples should be packages with any releases (like zip/tar). Perhaps we should just point people to the dfdl schemas if they want to find some examples, and just have very clear instructions on the wiki to run those. We also have a hello world example.
I'm thinking we should remove the daffodil-examples project completely. This also makes it so we don't have to worry about the daffodil-examples from getting out of sync with the DFDL schema github
